If only we could find the Wizard, he'd fix this mess right up. We should go find him, together.
The wizard of oz is about a simulated reality (land of oz) within a simulated reality (kansas, part of a world that only exists within a movie within the dreamlike illusion we call life). In the end the characters, who journey for answers and so on, find the answers were within themselves, then they have a great awakening. Etc.
